The short answer
Link to the next explanation a reader is likely to need, using text that describes the destination. A related-reading list should connect different useful tasks rather than repeat the same question on several pages. Build navigation from the reader's decision path, not an arbitrary link quota.
A worked example
A fictional article about placement budgeting links to a writing-package comparison because the two tasks are related but not identical. It does not need links to every image converter. The library can also link back to a marketplace hub, allowing the reader to apply the worksheet after understanding its assumptions.
A practical checklist
- For each article, identify one prerequisite and one useful next task. Check whether those topics already have a stable published page before adding a new one.
- Use descriptive anchor text and a real href. Review the destination without relying on a visual card or click handler alone to explain where it goes.
- Periodically check links after slug changes and archive decisions. Replace or remove stale destinations rather than leaving a related-reading section full of errors.
What to avoid
Avoid adding unrelated links merely to inflate the count or using the same vague 'click here' label for multiple destinations. A link should help someone understand what happens next. Keep private admin, account and utility URLs out of editorial discovery paths.
A useful follow-up
How many related links should an article have?
Enough to support a real next step without overwhelming the reader. Choose relevance rather than a fixed numerical target.
